Hello, I have a question. The battery is recognized but isn't charging. Could this be a software issue? I've already tried three other batteries, so I'd rule out the battery itself as the problem. The charger is also supplying sufficient voltage.

What could be wrong that's preventing the battery from charging?

The device in question is:
Acer Nitro AN515-55-79V5
FH52M LA-J891P Rev.: 1B

Thanks. I'm still checking the hardware before I start looking at the BIOS. Are there any common problems with the Acer Nitro AN515-55?

Status: I have a 12th generation Acer Nitro laptop with the main code HH514 LA-L973P REV 1A and the CPU is faulty. I replaced a CPU from an Acer mainboard of the same type and it worked, but the CPU had an error and couldn't enter Windows. Next, I replaced a CPU from a Dell laptop that was still working but had a VGA error. After replacing it, I flashed a new bios from the Acer manufacturer, but the machine still couldn't work. Can someone answer this question? Thanks.

Hi,

I've got this laptop for parts, no historical. When I try to power on, blue led lights up for 1s and stop, with or without battery. Battery is charging good - orange led is lit.
I've checked ALW voltage, 5v is here, but 3v is missing and I found a short on +3VS.
I've isolated this rail, and injected 1v/1a and found a heating resistor behind the CPU (on the other side), on boardview, it's connected to +3VS on one side, and +3VS_APU on other side.
I've removed it, no more short on +3VS, but +3VS_APU is still shorted (3Ω to the ground) and only other pins are under...

Looking for BIOS for this model.
Motherboard: HH514 LA-L974P Rev:1B
The BIOS should have 16MB, the chip is a Winbond 25W16JWSIQ

Need a clean BIOS for this if anyone has it. Cheers!

Hey guys,

i've got this laptop from a friend who gave it to me in a dead state.


The laptop wasn't working at all so i've began my search on the 19V power rail.
It was shorted to ground so i injected voltage and the only thing getting hot was my ground clip from my power supply.
I found that the +1.05V Rail for the Chipset was shorted. i removed the coil and it was shorted on the power delivery side.
The pch seems fine bc the rail has over 50 ohms after i removed the coil.

Still nothing was getting hot so i suggested the chip must...

Hello everyone,

I have this laptop came in with no power, shorted main power rail, after measuring resistance on coils, found out that VCC_GT was short (high side MOSFET part of the dual MOSFET was shorted)
After replace the MOSFET, laptop came back to life, pass memtest without any issue, but whenever I try to boot Windows 11 SSD or Windows 11 install from USB, laptop freeze I guess iGPU is partial dead since he received 19V when MOSFET got shorted.
So the question is, can we disable iGPU like hardware mod or BIOS mod?

Thanks by advance for your interest...
